Detailed description of the invention Referring now in detail to thedrawing, 10 designates pressing apparatus embodying the inventioncomprising a head 11 hinged as by hinge 12 to the buck 13. The head maybe provided with the usual handle 21 and may be swung down against thebuck 13. The head 11 comprises a usual head casting 15 provided at itsunderside with steam passages 16. The casting 1S is of curved transversecross-section as shown in FIG. 3. Attached to the underside of thecasting 15 is a transversely curved plate 17 provided with perforations1S to allow steam to pass downwardly. Mounted on the underside of thehead is a head pad 20.

The pad 20 comprises a top layer 22 of loosely woven or knittedFiberglas impregnated with Teflon. Asbestos may be used instead ofFiberglas, and the impregnated mateiral may be any other suitable highheat resistant material. It is found that a loose weave such as 10 by 10is suitable for the top layer 22. Beneath the layer 22 is a layer 23 ofmore closely woven or knitted Fiberglas, likewise impregnated with Teonor other high heat resistant material. The weave of layer 23 may be 32by 29. Nylon number 30 or 120 is suitable for this purpose. Below andcontacting the underside of the layer 23 is a layer 24 of knitted nylonpile fabric which is not impregnated.

The pile faces downwardly with the upper side of the layer 24 comprisingthe knitted back of the material. Lying against the underside of thelayer 25 is an under cover layer of closely woven Nomex clothimpregnated with Teflon. High heat resistant nylon number 30 or 120 maybe used for the cover cloth. Other high heat resistant material mayconstitute the impregnating substance. The layer 25 may have a turnedback sleeve 26 stitched as at 27 and receiving a tie cord 28. The cover25 extends beyond the layers 22, 23, 24 so that the sleeve 26 may bepulled up over the surrounding outer edges of the head and pulledtightly. The layer 25 as shown in FIG. 4 may be provided with grommets30 to receive the hooked ends 31 of coil tension springs 32 holding thepad on the head, in the usual well known manner. The resilient layer 24comprises the woven back 24a from which the pile 24b faces down.

The buck 13 may be of usual construction and may comprise a chamber 40to receive alternately steam and vacuum or vacuum alone. The chamber 40has a top wall 41 formed with perforations 42. The top of the buck iscovered by a buck pad 45. The buck pad 45 comprises an acceleratedvacuum pad portion 46. The pad portion 46 comprises a plurality oflayers of woven or knitted layers of Fiberglas. These are loosely wovenor knitted layers. A weave of by 10 has been found satisfactory. Theweave of the layers of the pad 46 may be similar to the loose weave ofthe layer 22 of the pad 20. Instead of layers of Fiberglas, Tefloncoated, Woven or knitted metal wire may be used for the acceleratedvacuum pad.

Overlying the pad 46 is a layer 47 of asbestos cloth used for ltrationand insulation. Overlying the layer 47 is a layer 48 of unimpregnatedfelted fabric made of nylon, Nomex or Arnel or the like material.Overlying the layer 48 is a thick layer 49 of perforated rubber orrubberlike material. The rubber may be natural or synthetic. Overlyingthe layer 49 is a layer 50 of asbestos and nylon woven together forminga iilter and starch retardent. Overlying the layer 50 is the cover layer51 which is similar to the cover layer 25 and is made of Nomex or otherhigh heat resistant nylon such as nylon number 30 or 120 impregnatedwith Tetlon. The cover layer 51 is of greater dimension all around thanthe layers 47, 48, 49, 50 and is turned back at its periphery to form asleeve 52 stitched in place by a line of stitching 53. The sleevereceives a tie cord 54 passing through the sleeve so that the pad may betightened around the buck and tied in such condition over the buck.

It will now be further understood that the bottom of the head pad andthe top of the buck pad 45 comprise covers made of Nomex or other highheat resistant nylon impregnated with Teflon or other high heatresistant material. As the head is moved down, these two cover layerstrap heat therebetween providing for dryer pressing and higher heattemperatures. The accelerating vacuum pad allows steam to come upthrough the pad faster.

The purpose of the rubber layer 49 is to provide resiliency to the buckpad. The purpose of the felted layer 48 of the buck pad is to provideresiliency and aid in preservation and insulation of the rubber layer49. The accelerated vacuum pad layers 46 prevent charring of the feltpad 48 and create faster drying of the garments being pressed. Theselayers 46 tend to trap air and keep it in, so as to reduce resistance tosteam or air passing therethrough. These layers 46 also act to filterthe steam.

The purpose of the pile fabric 24 of the head pad is to give resiliencyto the head pad and to filter the steam.

The covers and 51 stay dry because the Teflon impregnating the clothprevents absorption of moisture.

The asbestos cloth layer 47 is for the purpose of filtration andinsulation.

A metal peripheral frame 60 of angular cross-section may be riveted tothe layers 22, 23, 24 of pad 20, by rivets 61, if desired. A similarframe 62 may be riveted 4 to layers 46, 47, 48, 49 and 50 of pad 45, ifdesired, by means of rivets 63.

The Nomex or nylon 30 or 120 and the Teflon referred to herein have amelting point above 500 F.

In FIG. 8 there is shown a pad 100 illustrating a modied form of theinvention. The pad is to be disposed at the underside of a steampressing head 11, such as shown in IFIG. 3.

The method of making the pad 100 is illustrated in FIG. 7. In FIG. 7there is shown a flat metal grid plate 102. At the underside of plate102 is a layer 22, such as shown in FIG. 3. Against the underside of thelayer 22 is a layer 23, such as shown in FIG. 3. At the underside oflayer 23 is a layer 24, such as shown in FIG. 3 and which comprises thebacking 24a and the pile 24h.

At the underside of the layers 24 is a cover cloth 25 of the samematerial as the cover cloth 25 of FIG. 3 is made.

The plate 102 and the layers 22, 23, 24 and 25 are superposed andstitched together by a line of stitching 105. Thereafter a binding 106is wrapped around the entire registering peripheral edges of said layersand the binding is stitched through, as at 107. The binding 106 may bemade of Nomex or other nylon impregnated with Teflon. In other words thebinding 106 may comprise the same cloth as the layer 25.

Thereafter the flat plate 22 and the layers are pressed into the shapeshown in FIG. 8, to provide a concave bottom 108 from which an upwardlyextending rim portion 108a extends. The rim 108a is formed with aplurality of spaced through openings 109 through which extend rivets110.

Mounted on the ends of each of the rivets 110 is a lop 111. Engagingeach loop 111 is an S hook 112. The S hooks are interconnected bysprings 32 which attach the pad to the steam pressing head 11.

It will be noted that the grid plate 102 lies against the underside ofthe plate 17.

It will thus be seen that there is provided an apparatus and article inwhich the several objects of this invention are achieved, and which iswell adapted to meet the conditions of practical use.

As possible embodiments might be made of the above invention, and asvarious changes might be made in the embodiment above set forth, it isto be understood that all matter herein set forth or shown in theaccompanying drawings, is to be interpreted as `illustrative and not ina limiting sense.
